TOPIC: WHMCS Content Subscription Module

I am in search of a produce/service module in WHMCS that will place someone in a joomla 1.7 ACL group when they purchase a subscription to it in WHMCS. Once the subscription expires, the module will remove them from that ACL group.

Is this a project that I could hire you to do or do you know of an item that will do this or something similar that I could alter?
